Abstract

The PCE model is described in the "PCE Architecture" document and
facilitates path computation requests from Path Computation Clients
(PCCs) to Path Computation Elements (PCEs). This document specifies
generic requirements for a communication protocol between PCCs and
PCEs, and also between PCEs where cooperation between PCEs is
desirable. Subsequent documents will specify application-specific
requirements for the PCE communication protocol. This memo provides information for the Internet community.
